BEST MODE FOR CARRYING OUT THE INVENTION A circulating apparatus according to the present invention purifies and circulates bath water from a bath tub such as a swimming pool, a home bath, and a commercial bath. In the present invention, the commercial bath includes a hot spring, a public bath, a private bath, and various other bathing facilities.

The foreign matter removing means in the present invention is for removing relatively large dusts such as hair and paper, and a known dust remover can be used as such foreign matter removing means. It is preferable that when dust is accumulated in the dust remover, the cleaning time is automatically displayed due to a rise in pressure or a liquid level in the dust remover.

The contacting means in the present invention introduces the liquid from which the contaminants have been removed by the contaminant removing means and contacts the hardly decomposable organic substances such as fats and proteins in the liquid. It is a means to set up and promote an environment where useful microorganisms that can decompose and assimilate organic matter live. Here, setting and promoting the environment in which useful microorganisms inhabit means that if useful microorganisms themselves exist in advance, it is necessary to adjust the environmental conditions in which the useful microorganisms inhabit and proliferate. If only spores exist, the spores are germinated and the environmental conditions under which useful microorganisms grow and proliferate are adjusted. In the present invention, a contact means is employed as a means for maintaining such environmental conditions, and a preferred contact means is to use a soil compact mainly composed of humus.

[0013] The soil compact mainly composed of humus is mixed with a humus or a binder containing an eluting silica component.
After drying, it is a pellet obtained by molding, the pellet includes other inorganic materials (for example, minerals such as magnesium),
An elution restricting agent and the like can be contained. When minerals are contained, the effect of promoting the growth of useful microorganisms and the supply of minerals to the bath can be achieved. In addition, when the dissolution inhibitor is contained, the dissolution time of the pellet in water can be controlled, and the replenishment time can be controlled. The shape of the pellet may be any of a cylinder, a prism, a disk, and the like.

The spores of useful microorganisms or useful microorganisms may or may not be present in the soil compact. In the present invention, it is preferable to selectively use according to the environmental conditions in which the contact means is provided.

When useful microorganisms are present in the soil compact, the useful microorganisms can be inhabited by the contact means by using a hardly decomposable organic substance such as fat or protein as a nutrient source.
The environment for growing useful microorganisms is maintained by the eluted components of the humus.

On the other hand, when no useful microorganisms are present, the useful microorganisms can be converted from non-degradable organic matter as a nutrient source from various bacteria or spores mixed in the bathing water by the action of the components contained in the soil compact. It can be adapted to occupy a preferred species and proliferate.

The useful microorganism has a property capable of sterilizing non-useful bacteria (for example, Escherichia coli, spoilage bacteria, etc.), and the treatment solution of the present invention renders the non-useful bacteria sterile. Conventionally, chlorine sterilization is intended to sterilize Escherichia coli. Therefore, according to the present invention, there is a great effect that sterilization can be performed without chlorine sterilization. This is thought to be due not only to the action of useful microorganisms but also to the action of metabolites emitted by useful microorganisms.

In the present invention, in order to sufficiently exert the action of useful microorganisms or their metabolites, a liquid through a contact means is directly introduced without solid-liquid separation to provide a habitat for the useful microorganisms. In addition, a separation means is provided, which allows time for the decomposition and assimilation of the hardly decomposable organic matter by the useful microorganisms and exhibits a filtering action.

As the separation means, pumice having a microporous structure containing a leaching silica component is preferably used. The pumice contains a clay mineral or a silica component that can be eluted into water on a volcanic rock mountain. Since it has a microporous structure, it is possible to provide a place where a useful microorganism inhabits, and to provide a time allowance for the decomposition and utilization of the hardly decomposable organic matter by the useful microorganism.

The useful microorganisms or their spores have a microporous structure as a habitat and metabolites assimilate persistent organic matter. Substances that take a long time to assimilate (for example, fibrous materials)
Is taken up by useful microorganisms, but remains undegraded or decomposed into colloidal suspended substances, which are filtered through pumice having a microporous structure so as not to flow out of the separation means.

The contacting means and the separating means of the present invention may have a structure in which each of the above-mentioned soil compacts and pumice is filled in a separate tank, or may have a structure in which they are filled in the same tank.

In the contacting means and the separating means, it is more preferable to perform aeration from below the packing material, since it becomes weakly acidic due to oxygen and promotes an environment where microorganisms can easily live and propagate. In the present invention, a means for returning the water that has passed through the separation means to the bathtub is provided, and the return means forms a circulation circuit. A circulation pump is used as the return means in the present invention. In the present invention, pressurized circulation is performed by the circulation pump, and water purified by the action of useful microorganisms or metabolites thereof is always supplied to the bath tub, so that water exchange becomes unnecessary. In addition, the useful microorganisms are always activated during the operation of the present apparatus because a nutrient source and other environments suitable for propagation are provided, so that the purifying power of the present apparatus is not weakened.
